I really don't have a problem with the RFs.... had them with my 545. It also had a spare for "just in case". It's the NO SPARE thing that I'm not comfortable with.

Someone posted a situation where not having a spare caused them a real problem. I said that while having a spare would have helped that person the trade off is the thousands that would never use a spare. Having a spare takes up space, adds weight, and adds cost. All that when the vast majority of people will never use it.
